Part Number: EMB1499Q Other Parts Discussed in Thread: EMB1428Q Please advise,
I have em1402em controlled by external mcu. EMB1428 works fine with cell selection up to the moment when all switches are closed and EN signal goes high to 1.02V. From SPI…
Troy,
As these devices are meant to be used together by design (EMB1499Q and EMB1428Q) as specified in the datasheet, we don't have information on device behavior when used individually. If you are using the device differently than what we specify in…
Part Number: EMB1428Q hi,
I have a question about EMB1429 with EMB1499.
When i want to discharge, i send 0x90 to EMB1428, i receive 0xA9, but then i also receive 0x79, and the switch has not been closed.
When i want to charge, i send 0x10 to EMB1428,…
Part Number: EMB1428Q Hi,
I sent 0xF0 to EMB1428 and it return 0xAF. But only PSW3 is close. CSW7 to 0 are all open.
I've set 1499 FAULT PIN to 0.
And I saw someone got similar problem before. But TI FAE said 0xAF(Fault code 1010 is 1499 fault)
Please…
Other Parts Discussed in Thread: EMB1428Q , EMB1499Q Hello,
I'm designing active battery cell ballancer using EMB1428Q. The VSTACK input should be connected to the highest voltage in the battery stack. However, my battery stack will consist of 16 x 4.2V…
Part Number: EMB1428Q Hi,
We're developing EBM1428. But remove the EMB1499.
We have some SPI issue now.
Please check below picture.
This is our schematic:
We only modify MOSFET switch. And we made a EMB1428 only board for testing charge pump and…
Part Number: EMB1428Q Hello,
We have a custom design based on EMB1402 evaluation board, consisting of EMB1428 and EMB1499. This is used to charge discharge a stack of 2Volt batteries. The system functions(able to charge/discharge cells), but intermittently…
Part Number: EMB1428Q HI
At present, the debugging has been normal, and charge pump also has waveform, and I want to know what kind of waveform will be on the oscilloscope of the switch pin that should be turned on when the chip operates normally.
Attached…
Part Number: EMB1428Q Hi,
We've done testing our own board. The SPI is working fine. But we still cannot measure 1MHz square waveform between CEXT1 and CEXT2.
SPI can return what command I just send. Fault code is 0b000. We only connect SDI, SDO,…
Part Number: EMB1428Q Hi
I currently using EMB1428 alone does not match EMB1499.
How to set EN ,DONE, DIR, DIR_RT these pins?
If it need to reverse,what should I do?
Is it a normal NOT gate or a specific one?
Does the official have a reference code?
I still…
